At least one computer-readable medium on which are stored instructions that, when executed by at least one processing device, enable the processing device to perform a method. The method includes determining a peak-efficiency range of a set of one or more pumps. The peak-efficiency range has an upper limit and a lower limit. The upper limit has an associated stage-down pump speed and the lower limit has an associated stage-up pump speed. The pump speed of the set of one or more pumps is determined. If the pump speed of the set of one or more pumps exceeds the stage-down pump speed, an operating pump of the set of one or more pumps is deactivated. If the pump speed of the set of one or more pumps falls below the stage-up pump speed, an operating pump is added to the set of one or more pumps.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The medium of claim 1, wherein the peak-efficiency range is determined from a peak-efficiency curve.
3. The medium of claim 1, wherein the stage-down fluid-flow rate threshold is a function of the average fluid flow through each pump of the one or more operating pumps.
4. The medium of claim 1, wherein the stage-up fluid-flow rate threshold is a function of the average fluid flow through each pump of the one or more operating pumps.
5. The medium of claim 1, wherein the method further comprises delaying the activation or addition of an operating pump for a predetermined amount of time after determining the fluid-flow rate through the one or more operating pumps.
7. The medium of claim 6, wherein the peak-efficiency range is determined from a peak-efficiency curve.
8. The medium of claim 6, wherein the stage-up pump speed threshold is a function of the average fluid flow through each pump of the one or more operating pumps.
9. The medium of claim 6, wherein the stage-down pump speed threshold is a function of the average fluid flow through each pump of the one or more operating pumps.
10. The medium of claim 6, wherein the method further comprises delaying the activation or addition of an operating pump for a predetermined amount of time after determining the fluid-flow rate through the one or more operating pumps.
